The property is underlain by Toodoggone volcanic and volcani- clastic rocks, and possibly the Hazelton Group. Mineralization is hosted by structurally controlled quartz-calcite stockwork and breccia zones within large areas of weakly veined and hydrothermally altered rock. Multi-episodic mineralization and rebrecciation is evident in varicoloured crystalline and chalcedonic cross-cutting quartz veins and late stage calcite veins. Mineralization consists of pyrite, galena, sphalerite, rare chalcopyrite, acanthite, native silver and electrum. Alteration is highly variable in both extent and intensity and ranges from broad zones of propylitic (chlorite, epidote and calcite +/- pyrite) alteration to scattered narrow zones of silicification with minor clay alteration.
